DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] Referring to FIGS. 1, the shaft of the sun-shading big umbrella 1 of the present invention is comprised sequentially of a hollow lower sleeve 27, a lower positioning sleeve 23 connected with the former sleeve 27, an upper sleeve 20 and an upper positioning sleeve 14, an umbrella frame formed from an upper fixed collar 11 and a lower runner 19 connected respectively with a plurality of longer ribs 17 an shorter stretchers 18 is inserted into the shaft, the upper sleeve 20 is provided thereabove equidistantly arranged with a plurality of pin holes 21 for insertion of a latching pin 22, so that the lower runner 19 can be moved up to open and position the frame. Finally, a finishing top cap 10 of the umbrella is fixedly mounted on the upper fixed collar 11 to complete the sun-shading big umbrella 1. In which, the upper fixed collar 11 of the present invention is provided centrally with a longitudinal fitting-over hole 12, and also is provided horizontally at the positions connected to the ribs 17 with a plurality of through holes 13 communicating with one another. The through holes 13 also communicate with the longitudinal fitting-over hole 12 (as shown in FIG. 2). Thereby, the lamp strings 16 (with lamp bulbs) fixedly provided on the ribs 17 have their conductors extended from the bottom thereof through the through holes 13 and the fitting-over hole 12 to connect to a control circuit 15 fixedly provided in the upper positioning sleeve 14. The control circuit 15 is controlled by a lamp-controlling switch 25 and an LED indicating light 24 fixedly provided on the lower positioning sleeve 23. The lamp-controlling switch 25 and the LED indicating light 24 are further connected to a power supply connector 26 to be connected with an AC/DC circuit 28 provided in the hollow lower sleeve 27. The AC/DC circuit 28 is extended out of the shaft of the umbrella to connect with a power supply plug 30 added with a transformer 29; alternatively, as shown in FIG. 1a, the power supply connector 26 provided in the lower positioning sleeve 23 can be directly insertion connected with a dry battery 33 provided in the hollow lower sleeve 27; these both provide power for the control circuit 15.

[0019] Referring simultaneously to FIG. 5 and 3, in the entire circuit diagrams of the AC/DC circuit 28 and the control circuit 15 of the present invention, the AC/DC circuit 28 is composed of a simple bridge-rectifier and a capacitor; while the control circuit 15 is composed of a plurality of resistors, capacitors, diodes, transistors, a Zener diode, an oscillator 151 and a single chip 150. The control circuit 15 is connected to the power supply connector 26 to be connected with the AC/DC circuit 28 for supplying power, while pins nos. 1, 2, 17 and 18 of the single chip 150 are respectively connected to two lamp strings 16 which are respectively connected further to two opposite ribs 17. Pins nos. 16, 14 and 4 are connected to a pin no. 1 of the oscillator 151, while the pin no. 4 is connected further to pins nos. 5, 2, 3 and 8 of the oscillator 151; and a pin no. 13 of the single chip 150 is connected to the lamp-controlling switch 25 and the LED indicating light 24, a pin no. 6 thereof is connected to a pin no. 6 of the oscillator 151, and a pin no. 5 thereof is connected to a the pin no. 3 and a pin no. 4 of the oscillator 151, a pin no. 7 of the oscillator 151 is connected again to the pin no. 2. In this way, referring again to FIG. 2, after the plug 30 is inserted into a house-socket, the AC voltage of 120 V is transformed into a AC voltage of 28 V through a transformer 29, then is converted into a DC electric power through the AC/DC circuit 28, and then a stable DC voltage is provided through the Zener diode. At this time, if the lamp-controlling switch 25 is pressed down, the lamp strings 16 will have the following variations:

[0020] 1. When the lamp-controlling switch 25 is pressed down the first time, the single chip 150 receives a first series of signals from the oscillator 151, all the lamp strings 16 are lightened.

[0021] 2. When the lamp-controlling switch 25 is pressed down the second time, the single chip 150 receives a second series of signals from the oscillator 151, all the lamp strings 16 are lightened in a way as if a rotating lamp is rotated fast.

[0022] 3. When the lamp-controlling switch 25 is pressed down the third time, the single chip 150 receives a third series of signals from the oscillator 151, all the lamp strings 16 are lightened in a way as if a rotating lamp is rotated slowly.

[0023] 4. When the lamp-controlling switch 25 is pressed down the fourth time, the single chip 150 receives a fourth series of signals from the oscillator 151, all the lamp strings 16 are lightened in a way of fast flashing.

[0024] 5. When the lamp-controlling switch 25 is pressed down the fifth time, the single chip 150 receives a fifth series of signals from the oscillator 151, all the lamp strings 16 are lightened in a way of flashing slowly.

[0025] 6. When the lamp-controlling switch 25 is pressed down the sixth time, the single chip 150 receives a sixth series of signals from the oscillator 151, all the lamp strings 16 automatically function to go in circulations from the above second to fifth situations to continuously change the modes of lightening.

[0026] 7. When the lamp-controlling switch 25 is pressed down the seventh time, the single chip 150 receives a seventh series of signals from the oscillator 151, all the lamp strings 16 are extinguished.

[0027] The control circuit 15 of the present invention can also be added with a set of radio emitter/receiver 31 and 32, as shown in FIG. 4, the push button on the radio emitter 31 can completely correspond with the lamp-controlling switch 25, thereby, at any orientation within the scope (about 25 m) of the big umbrella 1, lightening can be controlled.

[0028] This is because that, on a prototype of the present invention, the circuit and the electric lines are arranged to be all provided in the shaft of the umbrella, this is convenient in assembling, and the electric lines will not be hooked and torn during the course of opening and collapsing the umbrella; and design of the control circuit is simple and tidy, all the lamp strings are parallelly electrically connected with one another, once one of the lamp bulbs is damaged, variations of changing of the lightening modes will not be affected. And more, the lightening can be controlled with a radio remote controlling mode, hence the present invention is more convenient for use.

[0029] The structure of such a lightening umbrella is simple and tidy, it can not only get rid of the defects resided in the conventional lightening umbrella having electric lines exposed to affect collapsing and opening of the umbrella, but also can get the effects that lights thereon can vividly change in their various lightening modes. The umbrella thereby provides the effects of illumination and decoration.
